God forbid you ask this question in a 4runner facebook group. People come out defending Hefty as if CBI just murdered their friend.
You cannot go wrong with either. It is pretty apparent that the 4runner people don’t realize what Hefty was before Chris himself got a 4runner and started making parts for it. Their work was not perfect. They made mistakes and, frankly put, shipped out lousy products. Since their redesign (of front bumper), the quality of fitment has dramatically increased. I still, however, do not recommend their powder coat.
Though I cannot speak for CBI products, they seem like good products. They have also had quality control issues in the past, but I’m not sure if they do now.
I will say that I trust the welds of the Hefty fabricators as much as I do Shrockworks. They can take a beating.
